    In many countries, the population is either declining or rapidly concentrating in big cities, which causes problems in the form of vacant houses. It is often challenging to keep track of the locations and the conditions of vacant houses, and for example in Japan, costly manual field studies are employed to map the occupancy situation. In this paper, we discuss a technique to infer the locations of occupied and vacant houses based on ambient WiFi signals. Our technique collects Received Signal Strength Indicator (RSSI) data based on opportunistic smartphone sensing, constructs hybrid networks of WiFi access points, and analyzes their geospatial patterns based on statistical shape modeling. In situ experiments in two residential neighborhoods show that the proposed technique can successfully detect occupied houses and substantially outperform a simple triangulation-based method in one of the neighborhoods. We also argue that the proposed technique can significantly reduce the cost of field surveys to find vacant houses as the number of potential houses to be inspected decreases.

    Language proficiency diagnosis is essential to extract fine-grained information about the linguistic knowledge states and skill mastery levels of test takers based on their performance on language tests. Different from comprehensive standardized tests, many language learning apps often revolve around word-level questions. Therefore, knowledge concepts and linguistic skills are hard to define, and diagnosis must be well-designed. Traditional approaches are widely applied for modeling knowledge in science or mathematics, where skills or knowledge concepts are easy to associate with each item. However, only a few works focus on defining knowledge concepts and skills using linguistic characteristics for language knowledge proficiency diagnosis. In addressing this, we propose a framework for language proficiency diagnosis based on neural networks. Specifically, we propose a series of methods based on our framework that uses different linguistic features to define skills and knowledge concepts in the context of the language learning task. Experimental results on a real-world second-language learning dataset demonstrate the effectiveness and interpretability of our framework. We also provide empirical evidence with comprehensive experiments and analysis to prove that our knowledge concept and skill definitions are reasonable and critical to the performance of our model.

    Owing to the widespread utilization of activity recognition, numerous deep learning models have been proposed to facilitate recognition in diverse contexts. Federated learning (FL) is an emerging learning paradigm that enables the collaborative learning of a shared model without compromising the data privacy of users. However, the assumption of FL is to rely on the annotated data on clients, which is difficult to acquire the annotations for human activity recognition (HAR) on all clients due to the lack of expertise or resource. Moreover, a general model is not suitable for each person due to data heterogeneity, resulting from the different physical characteristics and various contextual information. To this end, we propose a semi-supervised learning method for personalized federated HAR, in which clients have completely unlabeled data, while the server has a small amount of labeled data contributed by volunteers. Clients conduct unsupervised learning on autoencoders with locally unlabeled data to collaboratively learn a general representation model. The server conducts supervised learning on an activity classifier with labeled data stored on the server. After that, the shared model is personalized using individually pseudo-labeled data on each client side, wherein both confidence and uncertainty are taken into account concurrently, with the aim of achieving a balanced selection for assigning pseudo-labels to samples. We conduct extensive experiments with two different real-world HAR datasets, demonstrating the effectiveness of the proposed methods.

    Abstract

    In this paper, we propose a cross-language font style transfer system that can synthesize a new font by observing only a few samples from another language. Automatic font synthesis is a challenging task and has attracted much research interest. Most previous works addressed this problem by transferring the style of the given subset to the content of unseen ones. Nevertheless, they only focused on the font style transfer in the same language. In many cases, we need to learn font style from one language and then apply it to other languages. Existing methods make this difficult to accomplish because of the abstraction of style and language differences. To address this problem, we specifically designed the network into a multi-level attention form to capture both local and global features of the font style. To validate the generative ability of our model, we constructed an experimental font dataset of 847 fonts, each containing English and Chinese characters with the same style. Results show that our model generates 80.3% of users’ preferred images compared with state-of-the-art models.

    In recent years, there has been a growing interest in the application of Graph Convolutional Networks (GCNs) for classifying or generating human skeleton-based action sequences. Despite the progress in this field, there exists a relative dearth of research on the underlying mechanisms of how these network structures learn and represent the information features of the human skeleton. This paper proposes a novel GCN-based reconstruction network ST-ATGCN that utilizes spatial and temporal attention mechanisms for analyzing the extraction and reconstruction patterns of human action sequences. This versatile network can be effectively employed in a wide array of applications, including data compression, noise reduction, and interpolation. Experimental results on a public dataset demonstrate that ST-ATGCN network outperforms most of the currently prevailing GCN-based methods. This indicates the efficacy of the proposed network architecture in accurately extracting and reconstructing human skeleton information. Moreover, the reconstruction network exhibits proficiency in effectively restoring noisy action sequences.

    Exploring jump back behavior patterns and reasons in e-book system.
    <title>Abstract</title>With the increasing use of digital learning materials in higher education, the accumulated operational log data provide a unique opportunity to analyzing student learning behaviors and their effects on student learning performance to understand how students learn with e-books. Among the students’ reading behaviors interacting with e-book systems, we find that jump-back is a frequent and informative behavior type. In this paper, we aim to understand the student’s intention for a jump-back using user learning log data on the e-book materials of a course in our university. We at first formally define the “jump-back” behaviors that can be detected from the click event stream of slide reading and then systematically study the behaviors from different perspectives on the e-book event stream data. Finally, by sampling 22 learning materials, we identify six reading activity patterns that can explain jump backs. Our analysis provides an approach to enriching the understanding of e-book learning behaviors and informs design implications for e-book systems.

    Investigating course choice motivations in university environments
    <title>Abstract</title>Recommendation systems need a deeper understanding of users and their motivations to improve recommendation quality and provide more personalized suggestions. This is especially true in the education domain, the more about the student is known, the more useful recommendations can be made. However, although many studies on the course recommendation exist, studies on the students’ course selection motivations in universities are limited. This study investigates the factors that contribute to students’ choice when selecting courses in universities to better understand student perceptions, attitudes, and needs and leverage data-driven approaches for recommending and explaining the recommendations in university environments. A qualitative interview for university students (N = 10) comprised of open-ended questions as well as a questionnaire for students (N = 81) was conducted, aiming to investigate the main reasons behind their choices. The results of this study show that students highly value the course contents and the benefits of the course towards their future careers. Furthermore, students are influenced by other reasons such as the possibility of obtaining a higher grade, the popularity of professors, and recommendations from peers. Next, we extract the main categories of students’ motivations and analyzed the questionnaire data by employing statistical analysis methods as well as the k-means clustering algorithm to identify different types of students in terms of course selection. Based on our findings, we discuss implications for designing more personalized course recommendation systems.

    The COVID-19 pandemic has resulted in school closures all across the world, and lots of students have shifted from conventional classrooms to online learning. With the help of ICT technologies nowadays, learning online can be more effective in a number of ways. However, most of the online learning environments without instructors' attention may result in different learning patterns compared to the traditional face-to-face classroom. In this paper, we aimed at detecting the slide reading behaviors of the students by analyzing operational event logs from a digital textbook reader for a lecture offered in our university. We compared reading patterns between traditional face-to-face lectures and hybrid online lectures, our results show that online lectures lead to more off-task behaviors. Our analysis provides a rich understanding of e-book reading and informs design implications for online learning during the pandemic. The findings can also be used to improve the instruction designs and learning strategies.

    Exploring Factors that Influence Collaborative Problem Solving Awareness in Science Education
    This study designed a science course following collaborative problem solving (CPS) processes, and examined the effect on students’ CPS awareness. The Limnic Eruption CPS course was implemented using a Moodle system in a tenth-grade class. Considering the complex and coordinated nature of CPS, in order to improve CPS skills, it is important to identify what are related with the development of all sub-skills of CPS. Thus this study aimed to determine potential factors that affect the use of CPS skills in students’ motivational and behavioral dimensions. Multiple data sources including learning tests, questionnaire feedback, and learning logs were collected and examined by learning analytics approach. The relationships between students’ CPS awareness with their learning motivation and learning behaviors were explored. The research findings indicated a significant positive correlation between CPS awareness and certain learning motivation factors and learning behavior factors. Considering the students’ individual differences in learning abilities, we also compared the results of high and low performance groups. As a result, low performers’ learning motivation and learning behaviors were correlated with the social domain of CPS awareness, while those of high performers were correlated with their cognitive awareness.

    Despite the continuous growth of global Internet users, almost 4 billion people do not use the Internet. The offline population includes people who live in developing regions or rural aging communities. In this context, we propose a learning-support platform for learners without an easy, reliable, and affordable means to access digital learning environments on the Internet. Unlike existing systems that provide little support for efficient educational data collection from offline learners, our proposed platform combines delay-tolerant networking mechanisms and active learning-based model-driven crowdsensing techniques to deliver learning materials and collect educational data efficiently.

    © 2019, The Author(s). The purpose of this study was to explore the factors that might affect learning performance and collaborative problem solving (CPS) awareness in science, technology, engineering, and mathematics (STEM) education. We collected and analyzed data on important factors in STEM education, including learning strategy and learning behaviors, and examined their interrelationships with learning performance and CPS awareness, respectively. Multiple data sources, including learning tests, questionnaire feedback, and learning logs, were collected and examined following a learning analytics approach. Significant positive correlations were found for the learning behavior of using markers with learning performance and CPS awareness in group discussion, while significant negative correlations were found for some factors of STEM learning strategy and learning behaviors in pre-learning with some factors of CPS awareness. The results imply the importance of an efficient approach to using learning strategies and functional tools in STEM education.

    In this paper, we focus on optimizing the assignment of students to courses. The target courses are conducted by different teachers using the same syllabus, course design, and lecture materials. More than 1,300 students are mechanically assigned to one of ten courses taught by different teachers. Therefore, mismatches often occur between students' learning behavior patterns and teachers' approach to teaching. As a result, students may be less satisfied, have a lower level of understanding of the material, and achieve less. To solve these problems, we propose a strategy to optimize the assignment of students to courses based on learning activity analytics. The contributions of this study are 1) clarifying the relationship between learning behavior pattern and teaching based on learning activity analytics using large-scale educational data, 2) optimizing the assignment of students to courses based on learning behavior pattern analytics, and 3) demonstrating the effectiveness of assignment optimization via simulation experiments.

    This study investigates how we can understand students' actual status in C programming exercises from their learning activity logs. In a face-to-face course of C programming exercise, it is hard for a teacher to see who are in trouble from their apperance. It is not always true that typing something means he or she is making some progress. Therefore it is important to identify, or possibly even predict, students having difficulty from their activity patterns. Most of the prior work paid attention to only trial-and-error activities, such as compile results and execution errors. However, it tends to be overlooked that knowledge acquisition process is also worthy of attention. When a student encounters a compile error, they usually read textbooks to seek a solution. It is considered to be useful for the task whether he or she has an ability to find appropriate pages for error resolution. In this paper, we propose a method to predict whether a student can resolve errors or not. Based on students' activity logs collected from our programming environment and e-book system, we conduct experiments to show and discuss the prediction performance.

    Extended learning environments involving system to collect data for learning analytics and to support learners will be useful for all-age education. As the first steps towards to build new learning environments, we developed a system for multimodal learning analytics using eye-tracker and EEG measurement, and inclusive user interface design for elderly learners by dual-tablet system. Multimodal learning analytics system can be supportive to extract where and how learners with varied backgrounds feel difficulty in learning process. The eye-tracker can retrieve information where the learners paid attention. EEG signals will provide clues to estimate their mental states during gazes in learning. We developed simultaneous measurement system of these multimodal responses and are trying to integrate the information to explore learning problems. A dual-tablet user interface with simplified visual layers and more intuitive operations was designed aiming to reduce the physical and mental loads of elderly learners. A prototype was developed based on a cross-platform framework, which is being refined by iterative formative evaluations participated by elderlies, in order to improve the usability of the interface design. We propose a system architecture applying the multimodal learning analytics and the user-friendly design for elderly learners, which couples learning analytics “in the wild” environment and learning analytics in controlled lab environments.

    The aim of this research is to measure self-regulated behavior and identify significant behavioral indicators in computer-assisted language learning courses. The behavioral measures were based on log data from 2454 freshman university students from Art and Science departments for 1 year. These measures reflected the degree of self-regulation, including anti-procrastination, irregularity of study interval, and pacing. Clustering analysis was conducted to identify typical patterns of learning pace, and hierarchical regression analysis was performed to examine significant behavioral indicators in the online course. The results of learning pace clustering analysis revealed that the final course point average in different clusters increased with the number of completed quizzes, and students who had procrastination behavior were more likely to achieve lower final course points. Furthermore, the number of completed quizzes and study interval irregularity were strong predictors of course performance in the regression model. It clearly indicated the importance of self-regulation skill, in particular completion of assigned tasks and regular learning.

The behavioral measures were based on log data from 2454 freshman university students from Art and Science departments for 1 year. These measures reflected the degree of self-regulation, including anti-procrastination, irregularity of study interval, and pacing. Clustering analysis was conducted to identify typical patterns of learning pace, and hierarchical regression analysis was performed to examine significant behavioral indicators in the online course. The results of learning pace clustering analysis revealed that the final course point average in different clusters increased with the number of completed quizzes, and students who had procrastination behavior were more likely to achieve lower final course points. Furthermore, the number of completed quizzes and study interval irregularity were strong predictors of course performance in the regression model. It clearly indicated the importance of self-regulation skill, in particular completion of assigned tasks and regular learning.

    Low back pain (LBP) is a globally common condition with no silver bullet solutions. Further, the lack of therapeutic consensus causes challenges in choosing suitable solutions to try. In this work, we crowdsourced knowledge bases on LBP treatments. The knowledge bases were used to rank and offer best-matching LBP treatments to end users. We collected two knowledge bases: one from clinical professionals and one from non-professionals. Our quantitative analysis revealed that non-professional end users perceived the best treatments by both groups as equally good. However, the worst treatments by nonprofessionals were clearly seen as inferior to the lowest ranking treatments by professionals. Certain treatments by professionals were also perceived significantly differently by non-professionals and professionals themselves. Professionals found our system handy for self-reflection and for educating new patients, while non-professionals appreciated the reliable decision support that also respected the non-professional opinion.

    We propose a new change detection method using clickstream data collected through an e-Book system. Most of the prior work has focused on the batch processing of clickstream data. In contrast, the proposed method is designed for online processing, with the model parameters for change detection updated sequentially based on observations of new click events. More specifically, our method generates a model for an individual student and performs minute-by-minute change detection based on click events during a classroom lecture. We collected clickstream data from four face-to-face lectures, and conducted experiments to demonstrate how the proposed method discovered change points and how such change points correlated with the students’ performances.

    Towards pervasive geospatial affect perception
    Due to the enormous penetration of connected computing devices with diverse sensing and localization capabilities, a good fraction of an individual’s activities, locations, and social connections can be sensed and spatially pinpointed. We see significant potential to advance the field of personal activity sensing and tracking beyond its current state of simple activities, at the same time linking activities geospatially. We investigate the detection of sentiment from environmental, on-body and smartphone sensors and propose an affect map as an interface to accumulate and interpret data about emotion and mood from diverse set of sensing sources. In this paper, we first survey existing work on affect sensing and geospatial systems, before presenting a taxonomy of large-scale affect sensing. We discuss model relationships among human emotions and geo-spaces using networks, apply clustering algorithms to the networks and visualize clusters on a map considering space, time and mobility. For the recognition of emotion and mood, we report from two studies exploiting environmental and on-body sensors. Thereafter, we propose a framework for large-scale affect sensing and discuss challenges and open issues for future work.

    Relation Analysis between Learning Activities on Digital Learning System and Seating Area in Classrooms
    This paper discusses a relation analytics between learning activities and seating area in classrooms. Learning activities are collected via digital learning systems; including a learning management system, an e-portfolio system and an e-Book system. The activities are converted into barometers which indicate the amount of activities such as quiz scores, report scores, action frequencies on e-Books, length of journals, etc. The classroom is divided into 12 subareas, and the correspondence between students and the areas are also collected via the learning management system. We applied classical statistical analyses to the collected data. Through the experiments with about 200 students over 14 weeks, we found out that the seating area has strong relationship to learning activities.

    As smart technologies pervade our everyday environments, they change what people should learn to live meaningfully as valuable participants of our society. For instance, ubiquitous availability of smart devices and communication networks may have reduced the burden for people to remember factual information. At the same time, they may have increased the benefits to master the uses of new digital technologies. In the midst of such a social and technological shift, we could design novel integrated platforms that support people at all ages to learn, work, collaborate, and co-create easily. In this paper, we discuss our ideas and first steps towards building an extended learning analytics platform that elderly people and unskilled adults can use. By understanding the characteristics and needs of elderly learners and addressing critical user interface issues, we can build pervasive and inclusive learning analytics platforms that trigger contextual reminders to support people at all ages to live and learn actively regardless of age-related differences of cognitive capabilities. We discuss that resolving critical usability problems for elderly people could open up a plethora of opportunities for them to search and exploit vast amount of information to achieve various goals.

The proposed method is applied to the log data of 2693 students in 15 courses that were conducted with following the common syllabus by 10 teachers. The experimental results show that in the case where the same teacher is not included in both training and test data, the accuracy of prediction slightly lower. We also show that at the beginning of a course, it is better to construct a prediction model including various items of learning logs, however, in the latter half, it is better to update the model by using selected information only.

    Collaborative learning is defined as situations where multiple learners participate in solving common problems. Collaborative learning provides a way of building knowledge through activities of collaboration with others. Group work is a representative form of collaborative learning and has been used in higher education. In group work, however, one of the widely discussed issues is group composition. Students have different attributes including learning styles, background knowledges, gender, and so on. Typical group formations are homogeneous and heterogeneous compositions. Numerous work addressed the problem and evaluated how learning outcome varies between different group formations both in online and physical environments. In this study, we focus on the group formation for real-world collaboration. We introduce different types of grouping into a class of a theme-based course and discuss the effects of different learning styles in collaborative learning environment. Students are characterized according to Kolb’s learning style inventory and then grouped by homogeneous, heterogeneous, and random strategies. We investigate how intra-group interactions varies with different types of composition; we monitor the activity levels of every group and have students peer-review each other for quantitative evaluation of contributions. We find typical patterns of activities and contributions, and discuss their association to grouping strategies.

    This paper reviewed the previous studies with respect to education neuro and cognitive psychology research in elderly and suggested learning environments design with information and communication technologies for the elderly. In the relationship with education, elderly has less memorization, much time to be used to new environments, but aware of building new social relationships, tends to play important roles in learning community, according to the previous research review about learning behaviors using ICT and so on. Therefore, we extracted two perspectives for effective learning environments for the elderly: perception of the self that recognizes learning as a self-behavior and building social relationships. In the relationship with cognitive strategies, the importance of strategic support for cognitive function was extracted. Considering the above, collaborative learning environments that facilitate self-perception and cognitive strategies such as visualization of the relationships between self-learning and collaborative learning with the enhancement of reflection awareness should be one of the effective learning environments for the elderly.

    This preliminary study developed the concept map tool “BR-Map” using learning logs on eBook viewer, and investigated the relationships between self-regulated learning (SRL) awareness, learning behaviors (usage of BR-Map, and one-minute paper and report submission), and learning performance. Psychometric data and learning logs were collected in the lecture course, and their relationships were analyzed using Spearman’s correlation analysis. The results indicated that awareness of intrinsic value, use of cognitive learning strategies, and self-regulation had significant correlations with the usage of BR-Map. The awareness of cognitive learning strategies had significant correlation with standard deviation of one-minute paper submission hours. With regard to relationships between the BR-Map usage and learning behaviors, the relationships between the usage of BR-Map and one-minute paper submissions, which was a regularly weekly assigned task, were found.

    Real-time learning analytics system for improvement of on-site lectures.
    [Purpose]The purpose of this study is to propose a real-time lecture supporting system. The target of this study is on-site classrooms where teachers give lectures and a lot of students listen to teachers’ explanations, conduct exercises, etc. [Design/methodology/approach]The proposed system uses an e-learning system and an e-book system to collect teaching and learning activities from a teacher and students in real time. The collected data are immediately analyzed to provide feedback to the teacher just before the lecture starts and during the lecture. For example, the teacher can check which pages were well previewed and which pages were not previewed by students using the preview achievement graph. During the lecture, real-time analytics graphs are shown on the teacher’s PC. The teacher can easily grasp students’ status and whether or not students are following the teacher’s explanation. [Findings]Through the case study, the authors first confirmed the effectiveness of each tool developed in this study. Then, the authors conducted a large-scale experiment using a real-time analytics graph and investigated whether the proposed system could improve the teaching and learning in on-site classrooms. The results indicated that teachers could adjust the speed of their lecture based on the real-time feedback system, which also resulted in encouraging students to put bookmarks and highlights on keywords and sentences. [Originality/value]Real-time learning analytics enables teachers and students to enhance their teaching and learning during lectures. Teachers should start considering this new strategy to improve their lectures immediately.

    This paper investigates the precision of rapid clock synchronisation for ubiquitous sensing services which consist of multiple smartphones. Specifically, we consider scenarios where multiple smartphones are used to sense physical phenomena, and subsequently the sensor data from multiple distributed devices is aggregated. We observe that the accumulated clock drift for smartphones can be more than 150ms per day in the worst case. We show that solutions using the public Network Time Protocol (NTP) can be noisy with errors up to 1800ms in one request. We describe a rapid clock synchronisation technique that reduces drift to 10ms on average (measured by linear regression) and achieves pair-wise synchronisation between smartphones with an average of 27ms (measured by accelerometer), following a Gaussian-like distribution. Our results provide a lower bound for rapid clock synchronisation as a guide when developing ubiquitous sensing services using multiple smartphones.

    The leading cause of death during earthquakes is the collapse of urban infrastructures and the subsequent delay of emergency responders in identifying and reaching the affected sites. To overcome this challenge, we designed and evaluated a crowdsensing system that detects collapsed buildings using end-user smartphones as distributed sensors. We present our evaluation of smartphones' accuracy in inferring a building collapse by detecting falls onto solid surfaces, and estimating the false positive rate. Further sensors can present more detailed information about each potential collapse event. We conduct simulations to identify strategies for dealing with false-positive data under scenarios of varying population density. Potential building collapses can be determined with 95&#37; accuracy given 10 connected devices within a 125m radius, increasing to 99.99&#37; for 50 devices. End-user devices can proactively offer valuable help to emergency responders during earthquakes, potentially saving lives.

We describe a rapid clock synchronisation technique that reduces drift to 10ms on average (measured by linear regression) and achieves pair-wise synchronisation between smartphones with an average of 27ms (measured by accelerometer), following a Gaussian-like distribution. Our results provide a lower bound for rapid clock synchronisation as a guide when developing ubiquitous sensing services using multiple smartphones.

    The leading cause of death during earthquakes is the collapse of urban infrastructures and the subsequent delay of emergency responders in identifying and reaching the affected sites. To overcome this challenge, we designed and evaluated a crowdsensing system that detects collapsed buildings using end-user smartphones as distributed sensors. We present our evaluation of smartphones' accuracy in inferring a building collapse by detecting falls onto solid surfaces, and estimating the false positive rate. Further sensors can present more detailed information about each potential collapse event. We conduct simulations to identify strategies for dealing with false-positive data under scenarios of varying population density. Potential building collapses can be determined with 95% accuracy given 10 connected devices within a 125m radius, increasing to 99.99% for 50 devices. End-user devices can proactively offer valuable help to emergency responders during earthquakes, potentially saving lives.

    Community Reminder: Participatory contextual reminder environments for local communities
    Many projects have looked at how communities can co-design shared online repositories, such as Wikimapia and Wikipedia. However, little work has examined how local communities can give advice and support to their members by creating context-aware reminders that may include advice, tips and small requests. We developed the Community Reminder environment, a smartphone-based platform that supports community members to design and use context-aware reminders. We have conducted a one month field study of Community Reminder to crowdsource and deliver safety-relevant information in a local community. The results show the benefits of involving community members in reminder design and connecting different perspectives. We also show that the proposed approach can broaden participation in local communities. (C) 2017 Elsevier Ltd. All rights reserved.

    A new lecture supporting system based on real-time learning analytics is proposed. Our target is on-site classrooms where teachers give their lectures, and a lot of students listen to teachers' explanation, conduct exercises etc. We utilize not only an e-Learning system, but also an e-Book system to collect real-time learning activities during the lectures. The proposed system is useful for a teacher just before lecture starts and during the lecture. The system provides summary reports of the previews of given materials and quiz results. The teacher can check which pages were well previewed and which pages were not previewed by students using the preview achievement graph. Additionally, the teacher can check which quizzes were difficult for students, and the suggested pages that should be explained in the lecture to aid students. During the lecture, real-time analytics graphs are shown on the teacher's PC. The teacher can easily grasp students status whether or not students are following the teacher's explanation. Through a case study, we confirmed the effectiveness of the proposed system, in terms of high synchronization between a teacher and students, i.e., the teacher adjusted the speed of his lecture based on the real-time feedback, and many students followed the teacher's explanation.

    Using Learning Analytics to Support Computer-Assisted Language Learning
    Computer-assisted language learning (CALL) is often used as an approach to foreign language teaching and learning in higher education. The CALL course is offered at a national university in Japan to allow freshman students to perform self-regulated learning with e-learning materials for the purpose of developing language skills. However, as novice self-regulated learners, freshman students have low self-regulation skills and they are more likely to obtain lower achievement. In addition, it is difficult for instructors to grasp students' learning situation due to the large amount of evaluation work. Therefore, in this research, a total of 7,413,397 learning logs were analyzed, which were collected from 2,499 students' learning interactions in the CALL course. After that, a learning support system for freshman students is proposed. The system is provided for students and instructors through the learning dashboard. On the one hand, students can conduct self-monitoring and reflect their behaviors in a visual way. On the other hand, instructors can identify learning behavioral patterns and grasp individual learning situation to provide one-on-one instructions.

An RNN is a variant of a neural network that handles time series data. For this purpose, the learning logs from 937 students who attended one of six courses by two teachers were collected. Nine kinds of learning logs are selected as the input of the RNN. We examine the prediction of final grades, where the training data and test data are the logs of courses conducted in 2015 and in 2016, respectively. We also show a way to identify the important learning activities for obtaining a specific final grade by observing the values of weight of the trained RNN.

    In many countries, the population is either declining or rapidly concentrating in big cities, which causes problems in the form of vacant houses in many local communities. It is often challenging to keep track of the locations and the conditions of vacant houses, and for example in Japan, costly manual field studies are employed to map the occupancy situation. In this paper, we propose a technique to infer the locations of occupied houses based on ambient WiFi signals. Our technique collects RSSI (Received Signal Strength Indicator) data based on opportunistic smartphone sensing, constructs hybrid networks of WiFi access points, and analyzes their geospatial patterns based on statistical shape modeling. We show that the technique can successfully infer occupied houses in a suburban residential community, and argue that it can substantially reduce the cost of field surveys to find vacant houses as the number of potential houses to be inspected decreases.

    © 2017. Students' journal writings could be useful resources for teachers to grasp their understandings and to see their own teaching objectively. However, reading a large number of journals thoroughly is not always realistic for teachers. Although various automatic analysis methods have been proposed to understand learning journals, they does not necessarily fit needs of teachers and tend to overlook minor opinions. In this paper, we propose an interactive report tool for exploring journal writings. Focusing on the efficiency of reading learning journals, it employs weekly keywords extracted from journals as entry points for journal sentences. It enables us to read journal sentences selectively. The tool also provides lists of most used adjectives from week to week, which is helpful for teachers to grasp the temporal variation of opinions through a semester. We conducted a preliminary questionnaire about the usefulness of the report tool targeting teachers of the course "Information Science" in our university. Most of them evaluated our tool positively although the number of answers were small.

Reading textbooks on computers or hand-held devices enables us to track the learning activities of students regardless of situations. In our university, several courses for first year students employs our e-book system, and we have been collecting its usage logs. From the logs, it seems that the highlighter function of the e-book reader plays an important role in learning because it is used most by the students. Though many researches studied the effectiveness of e-textbooks, only limited studies addressed how students utilize highlighters and how marking activity affects their learning. In this paper, we focus on highlighted portions of e-textbooks, and analyze how students use highlighters in their learning. We also attempt to provide recommendations to students for highlighting based on the highlighter usage in other classes.

These courses commonly use the same lecture materials, but are conducted by different teachers. The new aspect of our research is that we perform cross analysis over courses. Most past researches focus on students' activities in a specific course, and give discussions about how the students behaved, how the behaviors differ from each other. In contrast, our research focuses on the course activities and conducts a comparison among courses. First, we begin with data alignment for row data to rectify a student activity every 10 seconds. Through our analytics, it becomes clear that whether students' activities varies with teachers or their teaching styles. In the experiments, we applied the proposed analytics to 1.1-million operation logs, and found out interesting characteristics through the comparison across courses.

    In recent years, the number of vacant houses is increasing in Japan, as the population decline in local communities. In this context, there is an urgent need to develop smart socio-Technical systems that enable effective use and management of vacant houses, thereby preventing them from having negative impacts on local communities. In this paper, we propose an approach to support community-centric use and management of vacant houses based on an integrated crowdsourcing platform. We describe our ongoing project in Kashiwa City, and argue for an open, inclusive, and community-centric distributed platform to cater for some of the important needs in the community.

    A number of local governments, businesses, and research institutions have discussed the usefulness and importance of "green networks" in recent years. However, most green sites are still perceived as isolated distributed patches, thereby potentially leading to their underuse and little awareness of their importance. We propose a participatory environment that can visualize connections of green sites based on the levels of visible green using celestial sphere images contributed by citizens. The system combines existing green coverage maps and smartphone-based image capture tools to show "green routes" in a city. We expect that the proposed approach can increase the networked uses of green resources, thereby increasing the awareness of green networks and potentially leading to collective efforts towards the development of richer connected green in cities.

    Pervasive communication technologies have opened up the opportunities for citizens to cope with disasters by exploiting networked mobile devices. However, existing approaches often overlook the brittleness of the technological infrastructures and rely heavily on users' manual inputs. In this paper, we propose a robust and resilient sensing environment by extending and integrating cooperative location inference and participatory sensing using smartphones and IoTs. The proposed approach encourages proactive engagement in disaster mitigation by means of everyday data collection and end-user deployment of IoT sensors.

    The Use of Historical Information to Support Civic Crowdsourcing
    Context-aware notifications cannot be designed easily without knowing which context-aware notifications will be triggered and responded in time. In this paper, we discuss methods to improve the design of context-aware notifications. Using the data from our prior experiment, we identify main factors that influence citizens' responses to notifications and evaluate the predictability of quick responses using a simplified method. We then propose a model for designing civic crowdsourcing tasks based on historical information. We believe that creating well-designed notifications can decrease receivers' workloads and simultaneously expands the positive impacts of civic crowdsourcing on the quality of life in the city.

    Quantitative Evaluation of Public Spaces using Crowd Replication
    We propose crowd replication as a low-effort, easy to implement and cost-effective mechanism for quantifying the uses, activities, and sociability of public spaces. Crowd replication combines mobile sensing, direct observation, and mathematical modeling to enable resource efficient and accurate quantification of public spaces. The core idea behind crowd replication is to instrument the researcher investigating a public space with sensors embedded on commodity devices and to engage him/her into imitation of people using the space. By combining the collected sensor data with a direct observations and population model, individual sensor traces can be generalized to capture the behavior of a larger population. We validate the use of crowd replication as a data collection mechanism through a field study conducted within an exemplary metropolitan urban space. Results of our evaluation show that crowd replication accurately captures real human dynamics (0.914 correlation between indicators estimated from crowd replication and visual surveillance) and captures data that is representative of the behavior of people within the public space.

    Crowd Geofencing
    Geofencing mechanisms allow for timely message delivery to the visitors of predefined target areas. However, conventional geofencing approaches poorly support mobile data collection scenarios in which experts need in situ assistance. In this paper, we propose crowd geofencing environments, in which a large number of crowdworkers generate geofences to support mobile experts. As a first step to open up the possibilities of crowd geofencing, we have tested its feasibility by collecting more than one thousand geofences in an unfamiliar city prior to the visit to look into urban water and air quality issues. Our experience has revealed the strengths and weaknesses of crowd geofencing in terms of geofence quality and crowd-powered situated actions.

    Context Weaver: Awareness and feedback in networked mobile crowdsourcing tools
    Mobile crowdsourcing allows people to collect data using a large pool of participants. In this paper, we focus on mobile crowdsourcing for citizens to solve local issues in context. We argue that such crowdsourcing environments need to support exploration, a continuous, opportunistic, and multi-perspective process that existing crowd sensing systems cannot easily support. We have developed a system called Context Weaver, which connects participants using networked mobile devices in order to support collaborative exploration, and conducted field trials to understand the effect of networking participants in the crowdsourced data-collection activities that encompass planning, execution, and analysis phases. We discuss a methodology for exploratory mobile crowdsourcing by citizens based on the provision of mutual awareness and rapid feedback in context. The proposed methodology can provide a basis for a model of networked mobile crowdsourcing which can exploit not only the man-power but also the creativity of citizens to gather relevant data.

    Recently, many civic engagement platforms have appeared on the web and for mobile devices to collect public comments and local information. However, it is difficult to cope with diminishing civic engagement due to the loss of diverse outdoor activities in towns using existing civic engagement platforms. In this paper we present Activity Recipe, a framework for supporting citizens to create and share activities in public spaces and thereby promoting their cooperative outdoor activities. We discuss the methods to 'spread' effective activities for local communities and cultivate citizens' awareness for these activities based on Activity Recipe.

    The increasing amount of mobility data introduces an opportunity to develop novel urban applications that are integrated with everyday practices. Although simple events (e.g., visits to places) can be inferred from mobility traces, events have very different meanings in different contexts. To contribute to the body of work that aims to uncover effective methods to integrate ubiquitous computing technologies in urban spaces and context, we discuss interpretation of ubiquitous events in urban computing: food-venue visits. Based on a survey and a small supplemental study, we identify the spatial and social contexts that influence the meanings of food-venue visits. We also suggest a possibility of novel technological support for eating out.

To validate Aquiba protocol, we have conducted comprehensive simulations by including small-scale and large-scale scenarios along with applying three movement patterns of human.

    As people increasingly use location-aware devices for various applications including way finding (Arikawa et al., 2007; Navitime, 2009) and safety-enhancement (Enhanced 911, 2009), there is a tangible need for better infrastructural support of location-based services. Localization has been and is one of the most prominent areas of ubiquitous networking research. Early location systems (e.g., the Active Badge Location System [Want et al., 1992]) were built to allow people in closed experimental environments to access location-relevant information and services, and, since then, there has been a great increase in the number of global positioning system (GPS)-enabled devices, including location-aware mobile phones, in our everyday environments. Today, location-based services can be deployed on these devices to support various activities in everyday life.

    Recently, global warming is a serious problem all over the world. Japan endeavors to promote using bicycles in order to protect environment. We developed a system for supporting cyclists by using the data from a bike sensor network. Cyclists lose comfort of riding when they need to go through crowded streets. We collect riding information obtained with a gyro sensor attached to handlebars of a bicycle. Based on such information, we then extract riding condition of cyclists. This paper presents the design and implementation of a Human Probe system that can collect and store sensor data to show comfortable cycling routes on a map.

    Human Probes, which are human integrated or embedded with sensors, allow the acquisition of a variety of contextual information, facilitate collaborative information sharing and community action as well as the provision of personalized services such as personal health management and context-aware advertisements. Recently, we have examined the usefulness of pressure sensors embedded in shoes [2]. In this demonstration, we extend our previous research on embedded pressure sensors by considering complimentary uses of accelerometers so as to capture precise and meaningful context in our daily lives. Pressure sensors and accelerometers are similarly useful for capturing the motion of pedestrians; however, the close examination of the signals from both sensors reveals the strengths and the weaknesses of each, and suggests the possibility of their complimentary use to support Human Probes.

    The ubiquity of sensing devices, including location-aware, sensor-enabled mobile phones, creates an opportunity to design a novel digital layer of a city, which senses and shapes the experiences of urban inhabitants. This paper explores a possibility of ubiquitous sensing devices to generate alternative social landscapes of a city, and facilitate universal communication. Sensors have critical dual roles in this process: (1) analyzing existing social relations, and (2) providing resources for establishing new relations. Several examples are discussed in relation to the latter role of sensors in shaping social landscapes, suggesting the possibility to create various representations that could support novel communication and collaboration practices.

    Askus: Amplifying Mobile Actions
    Information sharing has undeniably become ubiquitous in the Internet age. The global village created on the Internet provides people with instant access to information and news on events occurring in a remote area, including access to video content on websites such as YouTube. Thus, the Internet has helped us overcome barriers to information. However, we cannot conceive an event happening in a remote area and respond to it with relevant actions in a real-time fashion. To overcome this problem, we propose a system called Askus, a mobile platform for supporting networked actions. Ask-us facilitates an extension of the conceivable space and action by including humans in the loop. In Askus, a person's request is transmitted to a suitable person who will then act in accordance with the request at a remote site. Based on a diary study that led to detailed understanding about mobile assistance needs in everyday life, we developed the Askus platform and implemented the PC-based and mobile phone-based prototypes. We also present the results from our preliminary field trial.

    Portable sensory devices carried by humans-which are referred to as Human Probes-facilitate easy-to-use sensing and monitoring of urban areas. However, when each Human Probe individually senses and transmits information, the sensing activity is inefficient in terms of energy consumption. In this paper, we propose an Architecture of Quality-enhanced Urban Information Blending and Aggregation (Aquiba), in which the sensing activities carried out by the Human Probes are adjusted autonomously under different conditions. Aquiba involves cooperative sensing that helps in achieving high-fidelity sensing while minimizing overall energy consumption. To demonstrate the validity of cooperative sensing, we implemented a prototype device by using a commercial off-the-shelf mobile phone and conducted a field experiment. The experimental results show that Aquiba is capable of providing high-fidelity sensing and reducing energy consumption efficiently.

    Ad hoc networks enable application services in various environments including indoor/underground spaces and urban canyons
    however conventional positioning infrastructures such as the GPS generally do not work well in these environments. We propose a lightweight, RFID-based positioning system that can be installed quickly and easily at various sites of ad hoc application deployment. The system includes a novel device called RFID Tape, which allows for efficient deployment and maintenance of a series of RFID location reference points. Pedestrian devices obtain location information from RFID reference points, and use motion sensors and a P2P-based technique to allow for continuous positioning even when the reference points are sparse. The device and the mechanism together facilitate the provision of location-aware features in ad hoc applications. © 2008 IEEE.

    Ubiquitous computing in the real world: lessons learnt from large scale RFID deployments
    Ubiquitous computing technologies are slowly finding their way into commercial information systems, which are often constructed at considerably larger scale compared to what is possible in research demonstrators. Furthermore, lengthy and costly preparation or upgrade of existing infrastructures, training of employees and users in the new ways of working, controlled introduction of new functionality, features and services to manage risk, unexpected behaviors due to the wider variety of possible real-world situations, incremental approach to systems development so as to better identify successful aspects, regard for the economics of systems as a core requirement, and selection of open or closed systems are all issues that are mostly outside the scope of current ubiquitous computing research but play a critical role in industrial deployments. In this paper we review two case studies of fully operational Radio Frequency Identification-based systems: the Oyster card ticketing system used at the London Underground in the UK, and retail applications deployed at the Mitsukoshi departmental stores in Tokyo, Japan. We examine each case in terms of technologies, user interactions, and their business and organizational context and make several observations in each case. We conclude by drawing general lessons related to ubiquitous computing in the real world and identify challenges for future ubiquitous computing research.

    Individual, unaided human abilities are constrained. Media have helped us to transcend boundaries in thinking, working, learning and collaborating by supporting distributed intelligence. Wireless and mobile technologies provide new opportunities for creating novel socio-technical environments and thereby empowering humans, but not without potential pitfalls. We explore these opportunities and pitfalls from a lifelong-learning perspective and discuss how wireless and mobile technologies can influence and change conceptual frameworks such as the relationship between planning and situated action, context awareness, human attention, distances in collaborative design activities, and the trade-off between tools for living and tools for learning. The impact of wireless and mobile technologies is illustrated with our research projects, which focus on moving 'computing off the desktop' by 'going small, large, and everywhere'. Specific examples include human-centred public transportation systems, collaborative design, and information sharing with smart physical objects.

    Recent years' advances in information technology and system LSI technology are spreading computing resources into ubiquitous places in the real world. In such an environment, 'What we should not do' is important as well as 'What we can do', since the problem in the computer science directly results in the problem in the real world. In this paper, we discuss the possibility and challenges in the 'Digitally Named World', which is the environment in which 'radio frequency ID's (RFIDs) are attached to any goods in the world, and any objects in the real world can be found by the readers of the RFIDs and the networked database system. Especially, we address the problem of privacy and life-cycle management of the objects, and we propose the method for managing privacy about the relationship between objects and individuals.

    Distributed multiuser hypermedia environments provide not only information sharing mechanisms but also user collaboration/ communication facilities. The provision of integrated views of heterogeneous information resources is necessary to create common understanding among the users who are possibly distributed in terms of geography and time. However requirements of customization must also be considered since such diverse users would want to personalize views of shared information. In order to integrate views considering requirements of flexible customization we propose cooperative view mechanisms of Dexter-based hypermedia systems, introducing environmental objects and their participation relationships. The mechanisms instantiate deputies of hypermedia on screen using participation relationships of users, hypermedia components, and environments. The relationships are also used for the purpose of supporting awareness. Using a novel user collaboration facility, the relationships are visualized so that users can easily recognize other users and/ or user groups having the same, slightly different or very different views. Attributes of environment objects are discussed so that the mechanisms can be effectively utilized in computer-supported cooperative work settings such as distance presentations, virtual offices and virtual classrooms.

    Redundant network structures allow efficient retrievals. Procedures to design network structures that allow efficient retrievals [9] add redundancies into network structures. However, as redundancies increase, costs of updates increase. When network structures are redundant, costs of updates include costs of updating original data, checking consistencies, and updating derived data. This paper presents the super‐key condition to reduce the costs of checking consistencies in redundant network structures. First, constraints required to keep redundant network structures consistent are shown and then a sequence of processes to delete or insert a record in redundant network structures maintaining the constraints is given. Relationships between functional dependencies and updates are discussed to derive the super‐key condition. The condition classifies network structures regarding costs of the processes to delete or insert a record. Finally, a procedure to design network structures that satisfy the super‐key condition is given. The procedure may increase redundancies of network structures to reduce costs of updates.

    Current movie recommender systems often prioritize accuracy, overlooking the diversity of recommendations and user interaction experience. Addressing these gaps, we introduce a system featuring rating lists from user groups alongside user-controllable options. Besides preference-based movie recommendations, our system aggregates rating lists from user groups that share common characteristics with the user. Recognizing that users have varied tastes, including low-rated movies in the rating list and exposing rating lists given by user groups can offer valuable and diverse reference than user preference-based approach. Additionally, our system incorporates control options, aiming to improve the interaction experience by allowing users to participate more actively in the recommendation process.

    Recommending music to bar customers is an extremely difficult task without considering the mood of the bar environments. This paper proposes a multimodal mood detection mechanism that provides useful mood data for recommending music in bars. The proposed mechanism utilizes various sensor data representing alcohol concentration in the air, noise level, brightness level, crowd density, etc. to quantify the mood of the place environment using a simple mixed weight-based calculation.The resulting representations can be used to categorize or rate the mood in a bar, which facilitates the development of music recommendation systems for bar environments.

    GPT exhibits significant potential in interactive language learning. Referencing the communicative scenarios of daily life and adjust communication methods not only makes conversations more natural but also provides learners with content matched to their proficiency level. This paper examines the effectiveness of different design prompts and fine-tuning techniques to enable GPT to identify and analyze users’ language proficiency automatically, thereby adjusting communication methods such as sentence length and complexity of grammar or vocabulary. This approach provides learning content more suited to the learners’ current proficiency level.

    In the domain of group recommendation systems (GRS), addressing the preferences of individuals with similar tastes is of utmost significance. Given the inherent diversity of opinions within a group, existing GRS techniques typically aggregate individual preferences into a collective group preference for providing recommendations. This paper introduces an innovative approach to group recommendation systems, with a specific focus on small groups sharing common interests. We introduce a web-based restaurant recommendation system designed for increased user satisfaction within small-scale groups. Drawing insights from group decision-making literature, we propose a recommendation algorithm centered around leadership. The proposed algorithm is designed to foster consensus among group members, leveraging the dynamics of leadership, and ultimately increasing the overall satisfaction of the group with the recommended choices.

    Learning path recommendation in university environments based on sequence mining
    Learning path recommendation system efficiently guides learners by constructing appropriate learning sequences from recommended learning materials to reach their goals. However, supporting active learning in the learning path recommendation systems for university environments is different from conventional mechanisms for recommending relevant online courses such as MOOCs. This paper analyzed different learning path patterns of students at Kyushu University and discussed the challenges to recommend appropriate learning sequence in university learning environments. Then we proposed an approach to address the challenges by designing a learning path recommendation mechanism based on sequence mining.

    We propose crowd replication as a low-effort, easy to implement and cost-effective mechanism for quantifying the uses, activities, and sociability of public spaces. Crowd replication combines mobile sensing, direct observation, and mathematical modeling to enable resource efficient and accurate quantification of public spaces. The core idea behind crowd replication is to instrument the researcher investigating a public space with sensors embedded on commodity devices and to engage him/her into imitation of people using the space. By combining the collected sensor data with a direct observations and population model, individual sensor traces can be generalized to capture the behavior of a larger population. We validate the use of crowd replication as a data collection mechanism through a field study conducted within an exemplary metropolitan urban space. Results of our evaluation show that crowd replication accurately captures real human dynamics (0.914 correlation between indicators estimated from crowd replication and visual surveillance) and captures data that is representative of the behavior of people within the public space.

    In recent years, the number of vacant houses is increasing in Japan, as the population decline in local communities. In this context, there is an urgent need to develop smart socio-Technical systems that enable effective use and management of vacant houses, thereby preventing them from having negative impacts on local communities. In this paper, we propose an approach to support community-centric use and management of vacant houses based on an integrated crowdsourcing platform. We describe our ongoing project in Kashiwa City, and argue for an open, inclusive, and community-centric distributed platform to cater for some of the important needs in the community.

    Context-aware notifications cannot be designed easily without knowing which context-aware notifications will be triggered and responded in time. In this paper, we discuss methods to improve the design of context-aware notifications. Using the data from our prior experiment, we identify main factors that influence citizens’ responses to notifications and evaluate the predictability of quick responses using a simplified method. We then propose a model for designing civic crowdsourcing tasks based on historical information. We believe that creating well-designed notifications can decrease receivers’ workloads and simultaneously expands the positive impacts of civic crowdsourcing on the quality of life in the city.

    Pervasive communication technologies have opened up the opportunities for citizens to cope with disasters by exploiting networked mobile devices. However, existing approaches often overlook the brittleness of the technological infrastructures and rely heavily on users’ manual inputs. In this paper, we propose a robust and resilient sensing environment by extending and integrating cooperative location inference and participatory sensing using smartphones and IoTs. The proposed approach encourages proactive engagement in disaster mitigation by means of everyday data collection and end-user deployment of IoT sensors.

    Geofencing mechanisms allow for timely message delivery to the visitors of predefined target areas. However, conventional geofencing approaches poorly support mobile data collection scenarios in which experts need in situ assistance. In this paper, we propose crowd geofencing environments, in which a large number of crowdworkers generate geofences to support mobile experts. As a first step to open up the possibilities of crowd geofencing, we have tested its feasibility by collecting more than one thousand geofences in an unfamiliar city prior to the visit to look into urban water and air quality issues. Our experience has revealed the strengths and weaknesses of crowd geofencing in terms of geofence quality and crowd-powered situated actions.

    A number of local governments, businesses, and research institutions have discussed the usefulness and importance of "green networks" in recent years. However, most green sites are still perceived as isolated distributed patches, thereby potentially leading to their underuse and little awareness of their importance. We propose a participatory environment that can visualize connections of green sites based on the levels of visible green using celestial sphere images contributed by citizens. The system combines existing green coverage maps and smartphone-based image capture tools to show "green routes" in a city. We expect that the proposed approach can increase the networked uses of green resources, thereby increasing the awareness of green networks and potentially leading to collective efforts towards the development of richer connected green in cities.

    Recently, many civic engagement platforms have appeared on the web and for mobile devices to collect public comments and local information. However, it is difficult to cope with diminishing civic engagement due to the loss of diverse outdoor activities in towns using existing civic engagement platforms. In this paper we present Activity Recipe, a framework for supporting citizens to create and share activities in public spaces and thereby promoting their cooperative outdoor activities. We discuss the methods to ‘spread’ effective activities for local communities and cultivate citizens’ awareness for these activities based on Activity Recipe.

    The increasing amount of mobility data introduces an opportunity to develop novel urban applications that are integrated with everyday practices. Although simple events (e.g., visits to places) can be inferred from mobility traces, events have very different meanings in different contexts. To contribute to the body of work that aims to uncover effective methods to integrate ubiquitous computing technologies in urban spaces and context, we discuss interpretation of ubiquitous events in urban computing: food-venue visits. Based on a survey and a small supplemental study, we identify the spatial and social contexts that influence the meanings of food-venue visits. We also suggest a possibility of novel technological support for eating out.

    Crowd sensing systems can open up a vast design space for mobile and wearable applications to monitor, record, and use disaster information in context. This short paper presents a succinct overview of the recent developments of crowd sensing environments in this application domain based on a work-in-progress review of relevant literature and use cases. This leads to the discussions on the ways crowd sensing should complement the existing backbone infrastructures to capture more detailed, relevant and richer data in different contexts.

    Despite the pervasiveness of smart devices, meaningful data cannot be collected easily without an effective platform that meshes with human activities. In this paper, we explore the design space for mobile applications that recommend microtasks in public spaces. In particular, we take a close look at a public transportation environment and suggest some of the contexts in which microtask requests could be embedded. We then discuss a context-aware approach to microtasking in a city, as well as its implications for citizens.

    Crowdsourcing allows one to collect information from a large number of citizens relatively easily, thereby creating an opportunity to provide a novel technological means to view and imagine the city, complementing conventional geovisualization and urban simulation games. We postulate that the inflexibility of existing crowdsourcing frameworks can impose inherent limitations in terms of the imaginability of the city, and propose citizensourcing, which augments crowdsourcing with the mechanisms for supporting exploration and active participation in order to address the limitations. We then describe our experiences with the smartphone-based prototypes of the mechanisms, and discuss their implications for the design of citizensourcing environments.

Roles of such macroscopic awareness are examined based on the conceptual frameworks of distributed collaboration and spatial experiences.

    To seek and collect useful sensor data in a participatory sensing environment, participants should be able to coordinate their activities in a timely manner. However, existing systems deal separately with the "preparation time" to define the goal and method of sensing, and the "sensing time" in the field. Therefore, participants cannot easily modify the sensing method, including the collaboration setting, once they are out in the field. In this demonstration, we will present a system called Kitokito, which allows participants to easily create small sensing tasks, and iteratively modify the collaboration and sensing method during the "sensing time.".

    The proliferation of networked mobile devices that can capture and communicate various kinds of data provides an opportunity to design novel manachine sensing environments of which this paper considers participatory sensing. To achieve energy efficiency and reduce data redundancy, we propose Aquiba protocol that exploits opportunistic collaboration of pedestrians. Sensing activity is reduced according to the number of available pedestrians in nearby area. The paper investigates the benefit of opportunistic collaboration in large-scale scenarios through simulation studies. To take microscopic interaction of social crowds into consideration, we adapt the social force model and include it as one of three mobility models applied in our studies. Though the simulation results depend on mobility models, they validate the benefit of opportunistic collaboration employed by Aquiba protocol.

    Human Probes, which are human integrated or embedded with sensors, allow the acquisition of a variety of contextual information, facilitate collaborative information sharing and community action as well as the provision of personalized services such as personal health management and context-aware advertisements. Recently, we have examined the usefulness of pressure sensors embedded in shoes [2]. In this demonstration, we extend our previous research on embedded pressure sensors by considering complimentary uses of accelerometers so as to capture precise and meaningful context in our daily lives. Pressure sensors and accelerometers are similarly useful for capturing the motion of pedestrians; however, the close examination of the signals from both sensors reveals the strengths and the weaknesses of each, and suggests the possibility of their complimentary use to support Human Probes.

    Recently, global warming is a serious problem all over the world. Japan endeavors to promote using bicycles in order to protect environment. We developed a system for supporting cyclists by using the data from a bike sensor network. Cyclists lose comfort of riding when they need to go through crowded streets. We collect riding information obtained with a gyro sensor attached to handlebars of a bicycle. Based on such information, we then extract riding condition of cyclists. This paper presents the design and implementation of a Human Probe system that can collect and store sensor data to show comfortable cycling routes on a map.

    Portable sensory devices carried by humans-which are referred to as Human Probes-facilitate easy-to-use sensing and monitoring of urban areas. However, when each Human Probe individually senses and transmits information, the sensing activity is inefficient in terms of energy consumption. In this paper, we propose an Architecture of Quality-enhanced Urban Information Blending and Aggregation (Aquiba), in which the sensing activities carried out by the Human Probes are adjusted autonomously under different conditions. Aquiba involves cooperative sensing that helps in achieving high-fidelity sensing while minimizing overall energy consumption. To demonstrate the validity of cooperative sensing, we implemented a prototype device by using a commercial off-the-shelf mobile phone and conducted a field experiment. The experimental results show that Aquiba is capable of providing high-fidelity sensing and reducing energy consumption efficiently.

    The ubiquity of sensing devices, including location-aware, sensor-enabled mobile phones, creates an opportunity to design a novel digital layer of a city, which senses and shapes the experiences of urban inhabitants. This paper explores a possibility of ubiquitous sensing devices to generate alternative social landscapes of a city, and facilitate universal communication. Sensors have critical dual roles in this process: (1) analyzing existing social relations, and (2) providing resources for establishing new relations. Several examples are discussed in relation to the latter role of sensors in shaping social landscapes, suggesting the possibility to create various representations that could support novel communication and collaboration practices.

    Information sharing has undeniably become ubiquitous in the Internet age. The global village created on the Internet provides people with instant access to information and news on events occurring in a remote area, including access to video content on websites such as YouTube. Thus, the Internet has helped us overcome barriers to information. However, we cannot conceive an event happening in a remote area and respond to it with relevant actions in a real-time fashion. To overcome this problem, we propose a system called Askus, a mobile platform for supporting networked actions. Askus facilitates an extension of the conceivable space and action by including humans in the loop. In Askus, a person's request is transmitted to a suitable person who will then act in accordance with the request at a remote site. Based on a diary study that led to detailed understanding about mobile assistance needs in everyday life, we developed the Askus platform and implemented the PC-based and mobile phone-based prototypes. We also present the results from our preliminary field trial.

    Ad hoc networks enable application services in various environments including indoor/underground spaces and urban canyons; however conventional positioning infrastructures such as the GPS generally do not work well in these environments. We propose a lightweight, RFID-based positioning system that can be installed quickly and easily at various sites of ad hoc application deployment. The system includes a novel device called RFID Tape, which allows for efficient deployment and maintenance of a series of RFID location reference points. Pedestrian devices obtain location information from RFID reference points, and use motion sensors and a P2P-based technique to allow for continuous positioning even when the reference points are sparse. The device and the mechanism together facilitate the provision of location-aware features in ad hoc applications.

    Advanced communication technologies enable sophisticated safety-enhancing systems that exploit numerous computing devices embedded in our commuting environments. However, the complexity inherent in these systems, together with the contingency in their real-life use context, can create usability problems that undermine safety. In this paper, we discuss an integrated, user-centered approach to designing and evaluating RFID-enhanced commuting environments for schoolchildren. Our integrative context sensing and sensemaking infrastructure exploits embedded computing devices not only for enhancing safety but also for understanding user experiences and thereby facilitating iterative usability improvement.

    In this paper, we analyze security and privacy issues in RFID-based reference point systems, which seamlessly provide high resolution location information so as to enable innovative mobile applications. Our preliminary analysis revealed the significance of the labor cost in deploying RFID reference points; therefore, we carefully analyze several system architecture candidates in terms of deployment cost and security/privacy threats. Based on the analysis, we select a scalable architecture to avoid the bottleneck in deployment cost even though it can be less secure. Finally, we briefly discuss potential solutions for critical security and privacy issues in the selected architecture.

    Individual, unaided human abilities are constrained. Media have helped us to transcend boundaries in thinking, working, learning, and collaborating by supporting distributed intelligence. Wireless and mobile technologies provide new opportunities for empowering humans, but not without potential pitfalls. We explore these opportunities and pitfalls from a lifelong-learning perspective and discuss how wireless and mobile technologies can influence and change conceptual frameworks such as the relationship between planning and situated action, context awareness, human attention, distances in collaborative design activities, and the trade-off between tools for living and tools for learning. The impact of wireless and mobile technologies is illustrated with our research projects, which focus on moving "computing off the desktop" by "going small, large, and everywhere." Specific examples include human-centered public transportation systems, collaborative design, and information sharing with smart physical objects.

Our visions of digitally fluent and creative citizens are largely influenced by the visions, ideas, and experiences of Alan Kay and his colleagues. We view the Squeak system (Ingalls et al., 1997; Guzdial and Rose, 2002) as powerful learning tools and media for enabling both active independent learning and collaboration. A series of Squeak workshops were designed and conducted at two elementary schools, which will be the basis for designing further activities.

    The Passage mechanism introduced in this paper provides an easy and intuitive way to transport various types of digital objects by using also normal physical objects without any special identification tags. The current implementation of the Passage mechanism utilizes electronic scales and contact-free identification devices and thus allows for identification of arbitrary physical objects as well as immediate and unique identification of certain dedicated physical objects. The mechanism is used in various types of cooperative work scenarios in the i-LAND environment (Streitz, et al. 1999) that provides an essential part of the infrastructure for cooperative buildings.

    We describe the i-LAND environment which constitutes an example of our vision of the workspaces of the future, in this case supporting cooperative work of dynamic teams with changing needs. i-LAND requires and provides new forms of human-computer interaction and new forms of computer-supported cooperative work. Its design is based on an integration of information and architectural spaces, implications of new work practices and an empirical requirements study informing our design. i-LAND consists of several 'roomware' components, i.e. computer-augmented objects integrating room elements with information technology. We present the current realization of i-LAND in terms of an interactive electronic wall, an interactive table, two computer-enhanced chairs, and two "bridges" for the Passage-mechanism. This is complemented by the description of the creativity support application and the technological infrastructure. The paper is accompanied by a video figure in the CHI'99 video program.

    In distributed conference systems, participants get access to the shared documents through the computer network. The authors describe requirements in distributed conferences regarding access rights to shared documents. We give four categories of hypermedia representation based on access rights and two principles of human interface design to avoid mismatch between access rights and oral communication. We have developed the Channel Checker, which supports Non-WYSIWIS user interface for hypermedia based conferences. It allows participants to confirm users' access rights information and to communicate smoothly in conferences. By using this interface, users can synchronize the audio communication channel changes with their pointer on the shared document browser. The prototype of the Channel Checker is implemented on Java and JavaScript with an HTML browser.

    Materialized views are important in databases, particularly in data warehouses, where they are used to speed up query processing on large amounts of data. These views need to be maintained incrementally in response to database updates. In this paper we investigate the problem of incremental maintenance of a materialized view in response to changes to the base data. We show that a materialized view can be maintained without accessing the view itself by materializing additional relations. We firstly give an algorithm for determining what additional relations need to be materialize in order to maintain a view incrementally. We then propose an algorithm for updating the materialized view (and the additional relations) based on the optimized operator tree used for evaluating the view as a query. A materialized view is updated by propagating updates to the nodes of its operator tree in a bottom-up fashion, where each node contains a relational algebraic operator and computes an intermediate expression. Our algorithm derives the exact update at every intermediate node in the tree, including the materialized view. Finally, we compare our incremental algorithm with the naive algorithm that recomputes the view from scratch.

    Distributed multiuser hypermedia environments provide not only information sharing mechanisms but also user collaboration/communication facilities. The provision of integrated views of heterogeneous information resources is necessary to create common understanding among the users who are possibly distributed in terms of geography and time. However, requirements of customization must also be considered since such diverse users would want to personalize views of shared information. In order to integrate views considering requirements of flexible customization, we propose cooperative view mechanisms of Dexter-based hypermedia systems, introducing environmental objects and their participation relationships. The mechanisms instantiate deputies of hypermedia on screen using participation relationships of users, hypermedia components, and environments. The relationships are also used for the purpose of supporting awareness. Using a novel user collaboration facility, the relationships are visualized so that users can easily recognize other users and/or user groups having the same, slightly different, or very different views. Attributes of environment objects are discussed so that the mechanisms can be effectively utilized in computer-supported cooperative work settings such as distance presentations, virtual offices and virtual classrooms.

    The paper describes a concept and facilities of the VIEW Classroom, a distance education system supporting interactions between a teacher and students. In a classroom a basic interaction between them is performed by questions and answers. In distributed education systems such an one-to-many interaction frequently implies difficulties in selecting by a teacher essential questions, and causes overload of a teacher and delays in the answering. The VIEW Classroom System provides a facility for the teacher to specify key phrases associated with locations of the teaching material. These phrases can be referred by students in their questions. A teacher can select essential students' problems from a list of questions ordered either by the predefined priority or by the frequency of questions. To avoid delays in answering questions the system provides a question support facility which makes possible to answer some questions automatically, by reusing previous answers to similar questions. The VIEW Classroom System provides a question accumulation mechanism and a graphical user interface.

    We describe data structures that allow efficient updates of materialized classes derived from relationship of classes in object bases. Materialization of derived classes reduces costs of retrievals and increases costs of updates. Costs of updates increase remarkably when several paths of objects derive the same object. If object bases satisfy the superkey condition proposed in this paper, consistencies of object bases are maintained by local navigations and the remarkable increase of the costs is avoided. Any object base can be transformed to satisfy the superkey condition by adding extra classes and their objects. In this manner, increasing redundancies allows efficient updates.

    Redundant data for fast retrieval increase costs of updates in distributed multidatabase systems. In this paper, costs of updates are reduced by introducing further redundancies. Duplicate values - redundant data that are obtained from relationships of original values - must be updated to preserve their currency when original values are updated. To update duplicate values, relationships of original data are retrieved in order to determine which duplicate values must be updated. If a file with duplicate values satisfies the superkey condition introduced in this paper, we can perform the retrieval required for updates faster. Redundant data are added to a database site to satisfy the condition.

This preliminary study developed the concept map tool “BR-Map” using learning logs on eBook viewer, and investigated the relationships between self-regulated learning (SRL) awareness, learning behaviors (usage of BR-Map, and one-minute paper and report submission), and learning performance. Psychometric data and learning logs were collected in the lecture course, and their relationships were analyzed using Spearman’s correlation analysis. The results indicated that awareness of intrinsic value, use of cognitive learning strategies, and self-regulation had significant correlations with the usage of BR-Map. The awareness of cognitive learning strategies had significant correlation with standard deviation of one-minute paper submission hours. With regard to relationships between the BR-Map usage and learning behaviors, the relationships between the usage of BR-Map and one-minute paper submissions, which was a regularly weekly assigned task, were found.

    Relationships between Collaborative Problem Solving, Learning Performance and Learning Behavior in Science Education
    © 2018 IEEE. This study was designed to identify correlations between students&#039; awareness of Collaborative Problem Solving (CPS) and learning performance and learning behavior in science education. The topic of the course was Genetic Diseases which was implemented in a twelfth-grade class. To assess the effectiveness of this instructional design, and to find out potential factors that affect the using of CPS skills, multiple data sources including learning test scores, questionnaire feedback, and learning logs were analyzed. First, results indicated significant improvements in students&#039; knowledge acquisition and awareness of Participation and Learning and Knowledge Building in CPS during the course. Furthermore, when we investigated the correlations between CPS awareness and learning performance and learning behavior, the findings indicated significant positive correlations between students&#039; learning motivation and their awareness of CPS processes. However, there were negative correlations found between certain learning behavior factors with CPS awareness and learning motivation factors respectively.

    Learning path recommendation in university environments based on sequence mining
    Learning path recommendation system efficiently guides learners by constructing appropriate learning sequences from recommended learning materials to reach their goals. However, supporting active learning in the learning path recommendation systems for university environments is different from conventional mechanisms for recommending relevant online courses such as MOOCs. This paper analyzed different learning path patterns of students at Kyushu University and discussed the challenges to recommend appropriate learning sequence in university learning environments. Then we proposed an approach to address the challenges by designing a learning path recommendation mechanism based on sequence mining.

    Development of a Network Database Design Support System
    データベースにおける問題として,意味制約の保持と質問処理の効率化がある.ネットワーク構造に基づくデータベースシステムは,リンクでデータ間の対応を表しており,スキーマ設計では,構造の表す制約と質問処理の容易さを同時に考慮しなければならない.本稿では,従属性制約の保持し質問を効率よく処理できるネットワークデータベースを設計するための支援システムの開発について述べる.質問の処理効率は,質問に必要なデータの対応を容易に求めるための冗長なデータの付加によって向上する.このようなデータに対しては,従属性制約を保持を保持するための管理を要する.即ち,処理効率と冗長性の管理のトレードオフが重要な問題となる.本システムでは,質問処理とネットワーク構造の適合性のいくつかのクラスに基づき,この問題に対処している.There are two problems of databases, preserving semantic constraints and query processing efficiency. In database systems based on the network structure, we should consider both of the dependency constraints expressed by the structures and query processing efficiency at the database design stage. In this paper we discuss development of a system to support the design of network databases which preserve dependencies and process queries efficiently. Query processing efficiency is improved by adding redundant data to get the correspondence of data for the query easily. We have to manage these data to preserve dependencies. Thus the trade-off between query processing and management of redundancy becomes an important problem. The system deals with problem using classes of suitability of network structures for query processing.

    Improvement of a Network Structure for Data Updates and Its Evaluation
    ネットワーク構造は,リンクでデータ間の1対多の対応を表現しており,データベースの効率よい物理構造である.一般に,データベース設計時に従属性制約を考慮することで,データの冗長性を削減でき,更新時の制約保持を容易に行うことができる.ネットワーク構造では,構造が従属性制約を表現しており,かつ,検索処理効率も構造に依存しているため,両者を考えた設計が必要である.一般に,従属性制約を考慮して設計した構造に,冗長な構造を加えることで,検索処理効率もよい構造にすることが可能である.しかし,更新処理効率については,冗長な構造に,対応する部分のデータ更新を反映させねばならず,オーバヘッドが増加する.本稿では, このオーバヘッドをできる限り小さく抑えるための方法を提案している.オーバヘッドが大きくなるのは,冗長な構造に,対応する部分での更新が常に反映されるとは限らない場合であり,更新を反映するか否かを決定するための検索処理が必要となる.これを避けるため,冗長な部分に対応する構造のキーを含むレコード型により,冗長なレコード型への更新反映を管理する方法と,経路の重複を数え上げておき,同様の管理を行う方法とを提案し,両者の特性について述べる.

    Designing Link-Structured Physical Databases
    リンク構造では,リンクに沿ったデータ間の対応を効率よく求めることが可能である.リンク構造を用いたネットワークデータベースは検索の処理効率がよく,関係データベースでの結合処理効率化のための索引構造もリンク構造の一種であると考えられる.データベースの処理効率化の点から,リンク構造の導入は本質的であると考えられ,データモデルにかかわらず物理スキーマにリンク構造を用いることで,効率よいデータベースが実現可能となる.データベースの設計法としては,(1)実体関連図を用いた直感的な方法,(2)従属性制約に基づく方法(関数従属性,多値従属性等):意味制約を反映し,冗長性を低くできる,(3)検索処理効率を考慮した方法:特定の検索の効率がよい.冗長性が付加され更新処理効率は悪くなる,等がある.リンク構造は従属性制約を表現するだけでなく,構造が決定されるとその上で効率よく行うことができる処理とそうではない処理とが決まってくるため,設計時に従属性制約及び検索,更新の処理効率をあわせて考慮する必要がある.本稿では,まず更新処理に対して形式的な議論を行い,次に,従属性を反映し,検索処理,更新処理を効率よく行うリンク構造の設計法を示す.

    Retrieval for Updates in Object-Oriented Gatabases
    オブジェクト指向データベースではクラス同志がISA関連や参照関連を持つ。参照関連は、オブジェクトの対応関係であり、リンクを用いたデータ構造で表わすことができる。リンクによりデータの対応を表わすデータベースのデータ構造としては、ネットワーク構造があり、本稿ではオブジェクト指向データベースの参照関連をネットワーク構造として扱う。リンクを用いたデータ構造ではりンクを用いた効率のよい検索処理が可能である反面、柔軟性に乏しくデータベースの再構成が困難であり、リンクを使用できない検索については効率が悪い。従って、効率よく行うことが必要な質問処理を設計の際に考慮する必要がある。検索処理を考慮してネットワーク構造を設計する場合一般に冗長性が増し、冗長な構造に対する更新波及が起こる。更新波及では、対応し合うレコードを見つけて更新するかどうか調べるための検索が必要となる。本稿では、更新波及のための検索処理について考察し、更新波及の効率がよいネットワーク構造の構成について述べる。

Derived files are such files that are obtained by enforcing some operations on base files, and should be updated when the corresponding base files are updated. In this paper, we show how derived files are updated efficiently when base files are updated. Processes required for updating derived files are stated first, and these processes are examined to be performed quickly. Then, conditions of database schemas for efficient updates are presented.

    Keeping Consistencies of Materialized Derived Data in Federated Database Systems
    データベースシステム(DBS)の形態として,集中型,分散型,連合型,非連合型がある.前の二つの型のDBSは,単一のデータベース管理システム(DBMS)がデータベースを管理するが,後の二つの型のDBSは複数のDBMSから構成されており,マルチDBSと呼ばれる.データベースが世に現れてから現在までの間に,機械可読なデータ資源が様々な形で蓄えられてきた.今後も,二次記憶の低価格化,安価で高性能なワークステーションの普及などにより,世界中で運用されるDBSの絶対数や蓄積されるデータ資源の量は増加を重ねていくと思われる.このような状況でますます重要となるのは,複数のDBSに対するデータ操作機能を持つマルチDBSを提供し,冗長な大量データの効率よい利用を促進することである.マルチDBSに含まれるそれぞれのDBSを要素DBSと呼ぶ.マルチDBSには連合型のものと非連合型のものがあるが,非連合型のものは要素DBSが均一であることを要求し,自律的な要素DBSを取り扱うことができない.本稿では,連合型のマルチDBS(連合データベースシステム)を議論の対象とする.すなわち,要素DBSの分散性,異種性だけでなく,自律性も考慮した,マルチDBSにおける導出データの一貫性管理法について論じる.まず,要素DBS分散性,異種性,自律性を考慮した更新処理のモデルについて論じる.次に,具現化した導出データを局所的な一貫性管理が可能となるように配置する方法を示し,さらに,連合データベースシステムを,更新処理に関して互いに自律的なグループに分割して一貫性管理を効率化する方法について述べる.

When materialized functions summarize data in more than one component databases, costs of maintaing consistencies of the materialized functions are reduced in two manners. One is to create materialized functions that satisfy a local update condition presented in this paper, and the other is to group component database systems and utilize representative values of groups in summarizing data.

    SUPPORTING INTERACTION BETWEEN A TEACHER AND STUDENTS IN VIEW
    This paper describes the system to support interaction between a teacher and students in VIEW Classroom, a distance education system. In classes a basic interaction corresponds to answer questions from students by a teacher. In conventional classes, a teacher may not be able to answer all questions and he cannot know which question is important before the selection of a student. Two major functions are realized in the interaction support system of VIEW Classroom. 1) Classification of questions by meaning is realized. It can be used to select important questions. 2) Questions and corresponding answers are stored in database, so that related questions-answers can be displayed when a question is prepared.

    Capturing essential questions using question support fadlities in the view classroom
    © Springer-Verlag Berlin Heidelberg 1995.The paper describes a concept and facilities of the VIEW Classroom, a distance education system supporting interactions between a teacher and students. In a classroom a basic interaction between them is performed by questions and answers. In distributed education systems such an one-to-many interaction frequently implies difficulties in selecting by a teacher essential questions, and causes overload of a teacher and delays in the answering. The VIEW Classroom System provides a facility for the teacher to specify key phrases associated with locations of the teaching material. These phrases can be referred by students in their questions. A teacher can select essential students&#039; problems from a list of questions ordered either by the predefined priority or by the frequency of questions. To avoid delays in answering questions the system provides a question support facility which makes possible to answer some questions automatically, by reusing previous answers to similar questions. The VIEW Classroom System provides a question accumulation mechanism and a graphical user interface.

    コンピュータとネットワークの急速な発達を背景に、CSCWに関する研究が盛んに行われている。利用者が空間的時間的に分散している場合、その間の対話をいかに支援していくかということは重要である。これまでの研究では電話のような1対1の対話が主であり、講義における質問と回答のような1対多の対話について木格的に研究されたものは少ない。講義において教師は生徒から出される質問に全てに回答するわけにはいかず、だれの質問を優先すれば良いのか判断が難しい。生徒にとっては、自分の質問に対して回答をもらえない可能性が高くなる。また、生徒が過去の講義内容を忘れた時には、教師は過去に一度回答した質問にも改めて説明を繰り返す必要がある。現在我々の研究室では、データベース技術をコミュニケーションの基盤とするCSCW環境VIEW(Virtual Interactive Environment for Workgroups)の研究を進めており、その具体的な応用の一つに遠隔教育システムVIEW Classroomがある。上記の問題を解決するためVIEW Classroomでは、質問を「キーとなる文字列」と「質問メニュー」の利用によって定型化し、類似した質問を集計し数の多い質問や特定の「キーとなる文字列」を含む質問を優先して教師に表示したり、教師の回答を保存して類似した質問に対しては回答を自動的に再生する機能を提供する。

    Virtual Database Systems on Networks
    To utilize various information resources dispersed in wide-area networks such as the Internet, it is important not only to look for the related resources efficiently but also to integrate them for obtaining more effective answers. In this paper, we call a set of loosely coupled information resources a virtual database. In this paper, we take a heterogeneous distributed cooperative problem solver, Helios, as the framework for constructing virtual databases. As information resources are always varying in wide-area networks, virtual databases are also dynamic. Further, although conventional databases have used the closed world assumption, virtual databases are based on open worlds and their query processing should be different from conventional ones. In this paper, we discuss the significance of virtual databases, comparing with various softwares proposed for information retrieval tools in wide-area networks.

    Response Acquisition Facilities in a Distance Education System Utilizing Cooperative Hypermedia
    高度な技術者を育成したいという社会の要請とコンピュータの進歩によってネットワークを利用した遠隔教育システムの開発が各地で進んでいる。遠隔教育システム:VIEW Classroomは、ネットワークで接続したコンピュータを介し地域的かつ時間的に分散した教師と学生が行う指導や学習を効果的かつ円滑に支援する仮想教室システムである。著者らは、教師が文字・図形・動画で構成されたハイパーメディア教材を学生の画面へ提示して講義し、学生がその上へアンダーライン・記事・リンクを追加して自分向きのテキスト(ノート)を作成しながら受講するシステムを開発中である。現実の講義では、教師は説明をすると同時に学生の表情を観察しており、理解や興味の程度それに質問の有無などの反応を認識して説明の内容や順序を変更している。遠隔教育のためのビデオ映像中心のシステムが開発されているが、学生数が多い場合には画面に全ての表情や動作を表示できないため、反応を認識する問題は解決できない。このため、VIEW Classroomでは講義中の学生の反応を抽象化して収集し、学生の状態を把握する作業を支援する機構を導入した。特徴は次のとおりである。(1)ノートを作成する動作情報を収集し、学生の直接的な反応が把握できる。(2)学生の動作情報に一定の評価を与えて教師の画面へ表示し、理解度の把握を容易にする。(3)教師と学生へ反応を表示して環境を共有する。(4)変化しながら繰り返し利用される教材の特徴を活かし、評価の知識を蓄積する機構を持つ。本稿では説明に対する反応の収集と表示機能、および構造の設計について説明する。

    CSCW(Computer Supported Cooperative Work)のシステムにおいては, データベースによるデータ共有の支援が必要不可欠である一方, 利用者が共有文書に個人的な書き込みを加えたり表示方法をカスタマイズするなどの「個別化」の支援も必要とされている. この個別化機構は, サブグループ単位で部分的な個別化を行なうなど, 完全な共有でも完全な個別化でもない中間的な場合を支援するような柔軟なものでなければならない. 一方, このような協調作業システムでは, 互いに複雑な関連性を持つ大量のハイパーメディア文書を取り扱うため, ハイパーメディア空間全体のおおまかな構造を直観的にわかりやすく表示させるような視覚化機構も必要とされている[1]. 既存のハイパーメディア空間の視覚化システムの多くは, メディアをノードとし, ハイパーリンクをアークとしたグラフ構造を画面にマッピングする手法をとっている. しかしハイパーメディアのリンク構造は非常に複雑なため, 空間をグラフによって表示するとリンクが錯綜してしまうという問題がある. 我々の研究室では, 柔軟な個別化の管理のために「環境」という概念を提案している. 本稿では, ハイパーメディアオブジェクトとこの「環境」をもとに, 動的に個別化された作業空間を生成し利用者に提示する機構を提案する. 作業空間は3次元的に表現される. 実世界を模した仮想的な作業空間を生成することで利用者に直観的にわかりやすいインタフェースを提供することが出来る. 文書間の関連はボタンやハイパーメディア地図上の線だけでなく, 時間的空間的な位置関係や, 様々なメタファにより表現される.

    Elaborate Feedback Mechanisms for Distance Lecture Systems
    Due to the recent development of computer network technology, it is getting possible to realize our daily work in distributed network environment. For global networks how to reduce the use of video equipments which require wide frequence bands, how to realize distributed version of work which can be seamlessly connected to the corresponding real-world work, and how to realize computer-based useful functions which cannot be realized in the real-world, are major important problems. In this paper we will develop elaborate feedback mechanisms from audiences to be used for distance lecture systems. Feedback by video pictures of few selected audiences, or by extracted information of movement of audience is not enough for our purpose. We will show question-answer mechanisms to be used during lectures. The results can be used to determine contents of the lecture, and to improve lecture materials by storing the result to databases. One important problem is how to minimize time loss caused by such question-answer processes. Major functions can be realized by the Event-Condition-Action model which is commonly used in active databases. We are planning to integrate these functions with distributed active hypermedia VIEW Media, currently developed by our group.

    最近の計算機ネットワーク環境の発展によって日常行っている作業をネットワーク内で行なえる条件がととのいつつある。広域分散システムを考慮した場合、広域帯通信を必要とあるビデオをできる限り使わないで、いかに現実の作業とシームレスにするかということが重要な研究課題となっている。また、計算機利用の特色を生かして現実の作業ではできないことを実現することも重要である。本稿ではネットワークを用いた遠隔講演への応用を考えに入れた聴衆からのフィードバック機構について考察する。選択された個人の聴衆の顔のビデオや、聴衆のマウスの動き等を集約した形のフィードバックだけでは不十分であるため、講演中にアンケートをとり、そのフィードバックで講演方針を決めたり、その結果をデータベースに納めて資料の改良に役立てる方式を示す、この場合に、アンケートによる時間のロスをいかに減らすかが重要である。この機能は能動データベースに用いられる事象・条件・動作モデルで実現でき、研究室で開発中の分散能動ハイパーメディアシステムVIEW Mediaと統合する予定である。Due to the recent development of computer network technology, it is getting possible to realize our daily work in distributed network environment. For global networks how to reduce the use of video equipments which require wide frequence bands, how to realize distributed version of work which can be seamlessly connected to the corresponding real-world work, and how to realize computer-based useful functions which cannot be realized in the real-world, are major important problems. In this paper we will develop elaborate feedback mechanisms from audiences to be used for distance lecture systems. Feedback by video pictures of few selected audiences, or by extracted information of movement of audience is not enough for our purpose. We will show question-answer mechanisms to be used during lectures. The results can be used to determine contents of the lecture, and to improve lecture materials by storing the results to databases. One important problem is how to minimize time loss caused by such question-answer processes. Major functions can be realized by the Event-Condition-Action model which is commonly used in active databases. We are planning to integrate these functions with distributed active hypermedia VIEW Media, currently developed by our group.

    Awareness and Its Feedback Management Mechanisms in Collaborative Hypermedia Systems
    我々は現在, 協調作業支援システムの基盤となる協調型ハイパーメディアシステムVIEW Mediaを開発している。協調作業支援システムにおける重要な課題の一つに, アウェアネス支援が挙げられる。アウェアネス支援の目的は, 他者の存在や行動を伝達しコミュニケーションを支援することにある。これによって円滑に協調作業を進めることが可能になる。従来のアウェアネス支援の主流はビデオ画像を用いるものであったが, これに対してVIEW Mediaではメタファなどを用いる抽象的なアウェアネス支援を扱っている。抽象的なアウェアネス支援を行う場合, アウェアネスのフィードバックという概念が重要な要素として挙げられる。本稿ではアウェアネスとそのフィードバックを中心に, 通常のセキュリティを含めた機構について述べる。

    Navigation Sharing Mechanisms for WWW Information Search
    WWWの情報検索を支援する仕組みとして各種サーチエンジンが開発されてきた。この場合, 利用者は独自の経験と知識に基づいて情報検索せざるを得ない。しかし熟練者のナビゲーションや同じ興味を持つグループに属する人々のナビゲーション傾向を共有することで効率よく情報検索することができる。我々はこのようなナビゲーション履歴を利用者間で共有することにより情報検索を支援するナビゲーション共有機構を開発中である。この機構においては膨大な履歴データから注目視されているページや頻繁に辿られている経路などの特徴を抽出し, 有益なナビゲーションを提示する必要が生じる。本稿では利用者の複数のナビゲーション履歴から構成される統合化ナビゲーションオブジェクトについて述べ, そこから抽出される特徴に基づいてナビゲーションを構成し利用者に提示する方法について考察する。

    ALAN - K Project (Advanced LeArning Network in Kyoto) : Effort to Create New Learning Environments for IT Education
    The ALAN-K (Advanced LeArning Network in Kyoto) was started in September, 2002 by Kyoto University with the Kyoto City Board of Education and some public schools in Kyoto to achieve new learning environments supported by computer. In the last school year, we had several workshops in two elementary schools. These workshops were based on SqueakToys, which is a part of the Squeak system, an object oriented programming environment. Our visions in this project is largely influenced by the visions of Alan Kay [l], [2] and his colleagues and two of them had visited Kyoto as instructors in the first 2 workshops. After that experience, we designed and practiced a series of original workshops. This paper describes the start-up phase of the ALAN-K project.

    Experience of the Network Display System with RFID for Participants in an Academic Conference
    学術会議は,口頭発表や資料による形式的な情報だけではなく,参加者が面と向かって交流をすることにより非形式的に情報交換ができるという点に意義があると言える.しかし,学術分野の専門化と細分化が進む今,初めて面と向かった参加者どうしに,互いのネームタグに書かれた情報だけで有意義な交流のきっかけが十分に用意されるとは言い難い.我々は,居合わせた参加者間の関係を発見し大画面に表示するシステム「DeaiExplorer」を開発し,数百人規模の国際学術会議において利用した.本システムは,居合わせた参加者が持つ RFID タグに反応し,文献データベースから参加者や他の著者をノードとするグラフを生成する.本論文では,利用で得られた結果を用いて,本システムが参加者間の関係発見にどのような影響を及ぼしたかを定性的,定量的に明らかにし,今後のシステム設計および研究課題の展望を示す.Academic conferences offer informal as well as formal opportunities to interact with each other. However, the physical appearance of participants and the information printed on their conference badges could not be enough to provide the effective opportunities. We developed "DeaiExplorer", which is an RFID application that discovers interpersonal connections by allowing collocated conference participants to mutually reveal their social networks on a large display device, and deployed it at a recent international conference. The system responds to nearby participants and dynamically derives inter-connected social networks from a publication database. We address the uncovered requirement for the system and challenges with the experience.

    A System for Extracting and Managing Geospatial Environmental Information Utilizing Human Probe
    With the advent of wireless sensor nodes, we can create a system of environment monitoring in urban areas. Although variable sensors can be deployed densely in certain area, it is not cost effective to use sensors more than necessary. Instead of embedded sensors, we can utilize information emitted from walking people. Although the technique of localization is advanced, there still exists a location error. It brings a huge impact for mapping the data, especially in large scale. Based on the idea, we propose a system of extracting environmental information with considering degree of location error. In our system, we have extended WINFO+, previously developed system for broadcast personal sensed information, to overcome issues about a location error.

    A Simulation Study of Human-Probe Approach for Urban Sensing
    Portable sensory devices carried by humans-which are referred to as Human Probes-facilitate easy-to-use sensing and monitoring of urban areas. However, when each Human Probe individually senses and transmits information, the sensing is inefficient in terms of energy consumption. In this paper, we propose an architecture called Architecture of QUality-enhanced Information Blending and Aggregation (Aquiba), in which the sensing activities carried out by the Human Probes adaptively adjust under different conditions. Aquiba involves cooperative sensing that help in efficiently maintaining the desired sensing resolution while minimizing energy consumption. We study the performance of Aquiba by running simulations in which large-scale scenarios are considered along with a realistic movement pattern of Human Probes. The simulation results demonstrate that cooperative sensing is capable of providing the desired sensing resolution and reducing energy consumption.

    Human Probes : Towards the Integration of Sensing in Human Activities
    We introduce Human Probes, a novel approach to wide-scale sensing that considers the integration of sensing in human activities. The Human Probes approach leverages the ubiquity of mobile phones and allows mobile users to capture environmental and biological information as they go about their daily lives-working, playing, and moving (on foot, by car, by bike, or by public transport). This approach considers flows and activities of pedestrian crowds as well as various modes of their cooperation so as to complement and extend existing approaches. Furthermore, Human Probes can support urban sensing because they can provide a dynamic, easy-to-deploy sensing infrastructure in a complex urban environment where dense deployment of stationary sensing devices is not possible due to various physical and social constraints. We discuss relevant issues and research challenges to realize a meaningful socio-technical environment based on this approach.

    A Design of a Generating System of Dynamic Street-Based Image Flows utilizing Participatory Sensing Approach
    We propose a dynamic mechanism for generating a series of relevant images along streets using user-submitted photos. Such a mechanism can provide users with personalized, contextually-relevant " street view "images. The proposed mechanism is based on a novel multi-dimensional index called KDRN-Tree (KDTree with Road Network), which can process a street-based retrieval query efficiently by considering a road network structure. We introduce KDRN-Tree, and describe its design and implementation in detail. The results of our experiments show that KDRN-Tree is more efficient than KDB-Tree, and that it is feasible to realize a dynamic mechanism for generating street-based image flows using KDRN-Tree.

    Information of physical object is not linked and indexing like web world. Bacause of that, it is probably that we cannot find anything we need. Therefore, it is valuable that enabling to retrieve position of object and confirm how many what kind of things there are in an indoor space by physical objects construct links interactively. So, we constructed distributed physical objects management system, RW-Link+. By giving various information to things of the real world, RW-Link+ can keep a connection of things, and relationship between a thing and web world. In this paper, we present about implementation, experiment evaluation, future work of RW-Link+.

    A Design of a Dynamic Mechanism for Generating Street-Based Image Flows Assuming the Availability of Photographs Taken with Mobile Devices
    現在,Google Street Viewに代表される,写真を用いて仮想的に街を散策できるサービスが利用されている.しかしながら,ある定められた時間にのみ撮影された画像を用いる従来のサービスでは,季節,時間帯,個人の嗜好等,条件を考慮して多様な風景を画像を連続提示することができない.本論文では,条件に応じて適切な風景を再構成するサービスを実現するために,カメラ付きの携帯電話等を用いて集めた街の写真をデータベースに蓄積し,道路に沿って画像列を高速に検索できる動的ストリート画像フロー生成機構を提案する.一般に,多次元空間索引を用いれば,場所とそれ以外の属性値を指定して対応する写真を高速に検索することができる.しかし,従来のように幾何学的な分割に基づいてアクセスの効率化を行う索引手法を用いた場合,道路ネットワークのような実世界の構造に沿った問合せ要求を円滑に処理することが難しい.そこで我々は,道路ネットワークを考慮した索引手法であるKDRN-Tree(KD-Tree with Road Network)を提案する.KDRN-Treeは,道路ネットワークに対して形状正規化処理を施す一方で,KD-Treeの分割位置を道路境界にできるだけ近づけることで,道路に沿った問合せ要求を効率良く処理することができる.我々は,街中にて撮影した写真を実験データとし,問合せ処理の評価を行った.その結果,KDRN-Treeの有効性と実用的なシステムへの適応可能性を確認した.

    物理空間の各所に設置されたセンサのデータを統合的に検索し,適切なタイミングでユーザに情報やサービスを提供するためには,空間時系列データを高速に処理する必要がある.本論文では,大量の空間時系列データの高速な検索を可能にする空間時系列索引機構 I-Tree の構造と検索アルゴリズムについて述べ,人工的に生成した大量の人数計測データと市街地に設置した微気象センサのデータを用いた評価実験の結果を示す.I-Tree を用いれば,空間時系列問合せに対してユークリッド距離の近い系列を,従来手法よりも安定して高速に検索することができる.Fast and efficient retrieval of spatial time series data is indispensable for applications that must provide users with timely and relevant information and services using complex sensor data in the real world. This paper introduces an indexing mechanism called I-Tree, which allows for fast retrieval of a massive amount of spatial time-series data, and describes its structure and the search algorithms. We also discuss the results of our performance evaluation using a large amount of artificially-generated spatial time-series data as well as temperature data from micro-weather sensors deployed in a city. I-Tree allows for fast, Euclidean distance-based similarity search of spatial time-series under various conditions.

    Supporting Intellectual Collaboration Using Network Context
    人々の知識の相違や重なりを考慮して効果的にコラボレーションを支援するためには,従来のような場所,時間,プレゼンス等のコンテクストだけでなく,ソーシャルネットワークを含むコミュニティ構造に関連したコンテクストを体系的に考慮する必要がある.本稿では,研究者の学術的なコラボレーションを支援するコミュニティマッピングツールについて述べ,複数のネットワーク構造を考慮したコンテクストアウェアサービスの可能性を議論する.Understanding the differences and overlaps of users&#039; knowldege is important in systems that support intellectual collaboratoin. Therefore, it is desirable to capture and use community-relevant contexts such as social network structures as well as conventional contexts such as location, time, and presence. This paper describes a community mapping tool that provides context-aware services based on multiple network strucutures to support academic collaboration among researchers, and discusses the possibilities of novel context-aware services for supporting intelelctual collaboration.

    A Control Method for Bluetooth Proximity Sensing using User Context
    Bluetooth で近接性を取得する際,常時検索を行うことは消費電力やプライバシーの観点から適切ではない.そこで本研究では,取得した近接性から人間関係を推定するアプリケーションを前提として,スマートフォンに搭載されている他のセンサを用いることでユーザが静止して会話している場面を検出し,Bluetooth を起動する制御手法を提案する.Bluetooth has been used as a proximity sensor because of its feature: it can search nearby device within 10 meter. However, searching all the time consumes huge battery. In this paper, we introduce the Bluetooth controlling method that depends on user&#039;s context. We predict user&#039;s context using accelerometers and microphones on smartphone in the method. Finally, we show how much we can reduce power consumption.

    © 2014. The authors - Published by Atlantis Press.Crowdsourcing allows one to collect information from a large number of citizens relatively easily, thereby creating an opportunity to provide a novel technological means to view and imagine the city, complementing conventional geovisualization and urban simulation games. We postulate that the inflexibility of existing crowdsourcing frameworks can impose inherent limitations in terms of the imaginability of the city, and propose citizensourcing, which augments crowdsourcing with the mechanisms for supporting exploration and active participation in order to address the limitations. We then describe our experiences with the smartphone-based prototypes of the mechanisms, and discuss their implications for the design of citizensourcing environments.

    Rapid growth in communication bandwidth has enabled novel uses of mobile wireless technologies in areas such as smartphone-based user participatory sensing for disaster detection and mitigation. In this manuscript, we discuss novel approaches to resolve fundamental problems that currently hamper the effective utilization of user participatory sensing in this critical application domain. Our approaches to address major challenges related to energy efficiency, collaboration, privacy, ease of deployment, and robustness of communication can be integrated with external systems in a complementary manner to overcome the limitations of current disaster detection and mitigation systems that rely on expensive stationary devices.

    A Context-Aware Approach to Microtasking in a Public Transport Environment
    Despite the pervasiveness of smart devices, meaningful data cannot be collected easily without an effective platform that meshes with human activities. In this paper, we explore the design space for mobile applications that recommend microtasks in public spaces. In particular, we take a close look at a public transportation environment and suggest some of the contexts in which microtask requests could be embedded. We then discuss a context-aware approach to microtasking in a city, as well as its implications for citizens.

    Beyond mobile collaboration: Toward metropolitan-scale geocentric crowdsourcing
    This paper discusses an approach to designing a ubiquitous crowdsourcing environment based on the lessons learned from the experiences of developing mobile collaboration systems. A data-centric approach is introduced to exploit metropolitan-scale human-mobility data for the provision of macroscopic awareness about people and places, which can facilitate the design and use of a geocentric crowdsourcing environment. Roles of such macroscopic awareness are examined based on the conceptual frameworks of distributed collaboration and spatial experiences. © 2011 ACM.

    The proliferation of networked mobile devices that can capture and communicate various kinds of data provides an opportunity to design novel manachine sensing environments of which this paper considers participatory sensing. To achieve energy efficiency and reduce data redundancy, we propose Aquiba protocol that exploits opportunistic collaboration of pedestrians. Sensing activity is reduced according to the number of available pedestrians in nearby area. The paper investigates the benefit of opportunistic collaboration in large-scale scenarios through simulation studies. To take microscopic interaction of social crowds into consideration, we adapt the social force model and include it as one of three mobility models applied in our studies. Though the simulation results depend on mobility models, they validate the benefit of opportunistic collaboration employed by Aquiba protocol. Copyright 2010 ACM.

    Portable sensory devices carried by humans-which are referred to as Human Probes-facilitate easy-to-use sensing and monitoring of urban areas. However, when each Human Probe individually senses and transmits information, the sensing activity is inefficient in terms of energy consumption. In this paper, we propose an Architecture of Quality-enhanced Urban Information Blending and Aggregation (Aquiba), in which the sensing activities carried out by the Human Probes are adjusted autonomously under different conditions. Aquiba involves cooperative sensing that helps in achieving high-fidelity sensing while minimizing overall energy consumption. To demonstrate the validity of cooperative sensing, we implemented a prototype device by using a commercial off-the-shelf mobile phone and conducted a field experiment. The experimental results show that Aquiba is capable of providing high-fidelity sensing and reducing energy consumption efficiently.

    Language:English  

    We propose an RFID-based human probe positioning system for urban sensing. We call a person who has various sensors on his/her body Human Probe (HP). Our goals are (1) to estimate a position for HP which is based on location information of RFIDs and other HPs which hold position information with estimated error and (2) to manage and visualize sensor data considering a degree of position accuracy.

  • Designing for usability and safety in RFID-based intelligent commuting environments

    Shin'Ichi Konomi, Tonionori Saito, Chang S. Nam, Takahito Shimada, Yutaka Harada, Kaoru Sezaki

    Language:English  

    Advanced communication technologies enable sophisticated safety-enhancing systems that exploit numerous computing devices embedded in our commuting environments. However, the complexity inherent in these systems, together with the contingency in their real-life use context, can create usability problems that undermine safety. In this paper, we discuss an integrated, user-centered approach to designing and evaluating RFID-enhanced commuting environments for schoolchildren. Our integrative context sensing and sensemaking infrastructure exploits embedded computing devices not only for enhancing safety but also for understanding user experiences and thereby facilitating iterative usability improvement.
